HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 663, 424, 974 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 663, 424, 974 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 663, 424, 974 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 663, 424, 974 is 1.
HCF(663, 424, 974) = 1
HCF of 663, 424, 974 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 663, 424, 974 is 1.
Highest Common Factor of 663,424,974 is 1
Step 1: Since 663 > 424, we apply the division lemma to 663 and 424, to get
663 = 424 x 1 + 239
Step 2: Since the reminder 424 ≠ 0, we apply division lemma to 239 and 424, to get
424 = 239 x 1 + 185
Step 3: We consider the new divisor 239 and the new remainder 185, and apply the division lemma to get
239 = 185 x 1 + 54
We consider the new divisor 185 and the new remainder 54,and apply the division lemma to get
185 = 54 x 3 + 23
We consider the new divisor 54 and the new remainder 23,and apply the division lemma to get
54 = 23 x 2 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 663 and 424 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(54,23) = HCF(185,54) = HCF(239,185) = HCF(424,239) = HCF(663,424) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 974 > 1, we apply the division lemma to 974 and 1, to get
974 = 1 x 974 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 974 is 1
Notice that 1 = HCF(974,1) .
